The objectives of this experiment are exploring the suitable times and foliar fertilizer formula for growth and yield of maize. The experiment 1 was conducted under split plot in CRD. Main plot was a number of spaying times and sub plot was foliar fertilizer formula. Number of spaying showed no significant on plant height and shoot dry biomass. While SWE 20 ml and FK 75 ml showed significantly highest of shoot dry biomass. In experiment 2, the combinations between SWE and FK were tested within 5 formulas. Only FK 50 ml/20L showed a significantly highest in shoot dry weight, ear weight and seed weight. While SWE 20 ml plus FK 50 ml showed the lowest of root dry weight, 55.9 g and showed the highest of seed protein content up to 9.25 percent
